The New Testament reads the kinsman-redeemer law and the book of Ruth as a single doctrinal arc, fulfilled in Christ. Hebrews explains the structure with care:
Since then the children share in flesh and blood, He Himself likewise also partook of the same, that through death He might render powerless him who had the power of death, that is, the devil… Therefore, He had to be made like His brethren in all things, so that He might become a merciful and faithful high priest in things pertaining to God, to make propitiation for the sins of the people.— Hebrews 2:14, 17
The argument is precisely the kinsman-redeemer argument. The redeemer must be kin. Christ was not by nature human; He became human, deliberately, in order to qualify. He had to be made like His brethren in all things. Galatians 4:4 says it again, in a single sentence:
When the fullness of the time came, God sent forth His Son, born of a woman, born under the Law, so that He might redeem those who were under the Law.— Galatians 4:4–5
Born of a woman: the kinsman condition. Born under the Law: the position from which redemption was needed. Sent for the purpose of redemption: the willingness. And what He paid was sufficient:
Knowing that you were not redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers, but with precious blood, as of a lamb unblemished and spotless, the blood of Christ.— 1 Peter 1:18–19
Kin. Willing. Able. The three conditions the Law required of every go’el, Christ met perfectly. The closer kinsman in Ruth’s story refused because the cost would jeopardize his own inheritance. Christ’s redemption cost Him His life — and rather than refusing, He set His face toward Jerusalem (Luke 9:51) and went.
Job, reaching across the centuries from the very beginning of Israel’s long story, already saw it — the kinsman-redeemer of all his suffering, who would stand on the earth in the latter days:
For I know that my Redeemer lives, and at the last He will take His stand on the earth. Even after my skin is destroyed, yet from my flesh I shall see God; whom I myself shall behold, and whom my eyes will see and not another. My heart faints within me!— Job 19:25–27
The Hebrew word for Redeemer in Job 19:25 is go’eli — my kinsman-redeemer. Job did not yet know His name. But he knew He would live, and would stand on the earth, and would be flesh and blood as Job himself was — the kinsman who, in the latter days, would secure for him everything he had lost.
